Perl or perl, never PERL. perldoc -q '"Perl"' Sometimes that is good, sometimes bad depending on who wrote the Perl you are reading, it is one way to pick up very bad habits. Does the code you are reading have: use strict; use warnings; At the top? If not you may be better off walking away slowly and then checking out a book (see suggestion below) or one of the free online resources first, then come back to the code. http://learn.perl.org > My question is this - does PERL execute sequentially and "skip around" > embedded subroutines or > Does it execute them inline?

An excellent resource is also Learning Perl from O'Reilly and will get you all of the basics you will need and give you familarity with how to do things in a Perlish way.
